Description Jan Lieskovsky 2012-11-07 15:56:28 UTC

A security flaw was found in the way Plone, a user friendly and powerful content management system based on Zope, performed permissions checks on BLOBs stored on custom content types. A remote attacker could provide a specially-crafted URL that, when processed, would allow the attacker to obtain BLOBs even when they should not be accesible / visible to them.

Comment 7 Vincent Danen 2014-06-26 21:16:46 UTC

This issue may affect the version of plone as shipped with EPEL5, however the latest version there is 3.1.6 (and the latest 3.x release is 3.3.5, which was released a year prior to this flaw being discovered).  Given the age of the EPEL5 package and its lack of support, we do not recommend anyone use it.

This issue does not affect plone as provided with the conga package on Red Hat Enterprise Linux 5.

Statement:

Not vulnerable. This issue did not affect the versions of luci (as provided by conga) as shipped with Red Hat Enterprise Linux 5.
